Hi. Can someone point me to a good (and really basic) PDF file or text regarding Finite Element analysis? I would prefer it having an example where it would solve the 1D heat equation or the Laplace equation so I can extend what I know from finite difference methods to it. Sorry if this seems too much, but I seriously cannot understand the text that I keep on finding. I am trying to study these methods on my own as I wanted to know the methods well (and at the bare minimum, execute manual calculations regarding these), as I believe knowing the method's concept is important before using programs that would execute them easily (I don't want to use programs blindly). I am asking for help because what happens is that every single paper I find follows a single format: It would introduce the big three PDEs, then it would show the advantage of using numerical solutions, then it would then introduce (apparently) weak and strong formulations and there would be integrations out of nowhere. Basically everything went ballistic lol and I am so inebriated now Thank you very much for your help.
